Application filed August 31,1905. Serial 110.276.628.

To all whom, it may concern:

Be it known that I, BONIFAZIUS KRAMPF, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Glaziers Points, of which the following is a specification.

This invention relates to an improvement in glaziers points, and has for its object to provide a device that is particularly adapted for securing panes of glass in the frames used in the construction of hothouses in which the glass is arranged within the frame with their lower edges overlapping and resting upon the lower glass for the purpose of shedding water.

A further object is to provide a device that is exceedingly cheap and simple in construction, easy of attachment, and one that will 1 is connected and securely hold the glass within the frame and against a sliding as well as an upward movement.

With these objects in view the invention comprises certain peculiar details of construction, as wili be fully described in the following specification and pointed out in the claim, reference being had to the drawings, in which Figure 1 is a perspective view of a portion of a frame of a hothouse to which the glass showing my improved point in position. Fig. 2 is an enlarged detail plan view of the same. Fig. 3 is a detail sectional view drawn on about the line 3 3 of Fig. 2. Fig. 4 is a perspective view of one of the points, and Fig. 5 is a similar view looking in a different direction from that shown in Fig. 4. Figs. 6 and 7 are detail views of a modified construction.

In the drawings, A designates the shank of the point, which in the construction shown in Figs. 1 to 5, inclusive, of the drawings is of an even width throughout its entire length and tapering upon its upper and lower side from its reduced end in a point B. Upon one side and at the broad end the shank is formed with a raised portion C, that provides a shoulder D, upon one surface of the shank, and from the opposite sides of the said raised portion project lateral extensions or flanges E, the lower faces of which are adapted to contact with the surface of the glass panes or panels, while either side of the shank is adapted to engage the edge of the glass.

As before stated, my improved point is esone end to the other and terminating at,

pecially adapted for securing panes of glass in the frames used in the construction of hothouses in which one pane of glass overlaps the other, and by reference to Figs. 1, 2, and 3 of the drawings, it will be seen that the panes are held within the frame by driving the points in the wood at the lower end of the glass, with the shank engaging the edge and one of the lateral extensions or flanges extending over and engaging the broad surface. By this arrangement it will be seen that each point serves the double purpose of holding the two panes of glass against an upward movement and'also against slipping or. a sliding movement within the channels of the frame.

With the diamondshape points now in use no provision is made for holding the glass in position other than to prevent an upward movement thereof, which are thus left free to slide unless a nail is driven in to hold them, and to insert a new glass, should one be broken, necessitates the removal of all the points, as well as the nails but with my construction it will be readily understood that should a pane or panel be broken the adjacent ones will be firmly held in position, and to insert a new glass necessitates the re moval of the points only at one (the upper) end of the glass, when a new pane may be in- 'serted and the points replaced.

It will also be understood that the flanges E orm a head, as it were, for the points and provide a surface by which the points may be driven into the frame.

In Figs. 6 and 7 of the drawings I show a slight modified construction in which the point F is made of galvanized sheet metal of substantially triangular shape with its central portion at one side pressed or stamped upwardly to provide a ridge G, flat upon its sides, and with a square shoulder H at about the center of the point. In this construction the end F forms the shank, which is driven in the sash or frame, so that the portion G rests against the edge of the glass and the surfaces adjacent thereto rest upon the broad face of the glass and hold it in position the same as the point shown in Figs. 1 to 5 of the drawings.

From the foregoing it will be seen that I provide an exceedingly cheap, simple, and highly-efficient device capable of meeting all the requirements and overcoming the obj ections of the present manner of holding the glass in the frames.

IIO

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is 4 A glaziers point comprising a tapering shank portion which terminates at one end. in a point and at its opposite end into a raised portion 'the'forward end of said raised portion extending Vertically from the shank BoNiFAZiUs KRAMPF.
